What is the reason for infant hypoxia? What is the reason for infant hypoxia?

Babies will experience hypoxia in their bodies, and parents must be aware of this. When the baby's body is obviously different from the usual state, you must pay attention to whether the baby is normal.

Causes of hypoxia in babies

3 major reasons for fetal hypoxia

Signs of fetal hypoxia in the uterus can endanger the health and life of the fetus, which is called fetal distress. The causes of fetal distress can be summarized into three categories.

1. Maternal factors: insufficient oxygen in the mother's blood is an important reason, such as pregnancy-induced hypertension, severe anemia, carbon monoxide poisoning, shock caused by various reasons, and acute infection fever.

2. Placenta and umbilical cord factors, obstruction of umbilical cord blood flow, such as the umbilical cord is too long or too short, the umbilical cord is entangled, knotted, twisted, and the placenta is ineffective. Some pregnant mothers suffer from hypoxia in the fetus at 3 months of pregnancy due to poor placental function.

3. Fetal factors: the fetus suffers from severe congenital cardiovascular disease, intracranial hemorrhage, fetal malformation, etc. Fetal distress mainly occurs during labor and can also occur in late pregnancy.

How to prevent fetal hypoxia

Fetal hypoxia has a great impact on the baby's intelligence and physical health, and even on the fetal life safety. Therefore, expectant mothers should actively understand the symptoms of fetal hypoxia and what to do if the fetus is hypoxic, so as to effectively prevent fetal hypoxia and avoid some dangers. Here are some ways to prevent fetal hypoxia.

1. When a pregnant mother is diagnosed with intrauterine growth retardation, the first thing to do is to find out the cause of the disease and rule out fetal malformations through B-ultrasound and other methods.

2. Pregnant mothers should receive treatment according to the cause of the disease, and refrain from smoking and drinking; pay attention to bed rest, preferably lying on the left side, and can use drugs such as salbutamol to relax the uterus and dilate blood vessels, so as to improve the blood supply to the placenta.

3. Nutritional supplement: In addition to diet therapy, glucose solution and amino acids can also be infused to promote fetal development; intermittent oxygen inhalation is given every day to prevent or relieve fetal intrauterine hypoxia.

4. It is very important to strengthen fetal monitoring, because the baby may suffer from intrauterine hypoxia or even death at any time in the womb. Regular fetal heart rate electronic monitoring, B-ultrasound examination and fetal placental function testing can help to detect fetal intrauterine hypoxia in time and deliver the baby at the right time. Around 36 weeks of pregnancy is the period when intrauterine growth retardation babies are prone to intrauterine fetal death, so monitoring should be strengthened.

Why does hypoxia occur?

If you often have hypoxia, the early movement will increase significantly, that is, the fetal movement will be frequent; if the hypoxia lasts for a long time, there is no strength to move, and the fetal movement will decrease significantly. Therefore, it is recommended that you pay attention to the fetal movement in the uterus in the late pregnancy.

There are many factors that cause intrauterine hypoxia, such as pregnant women with some diseases, such as diabetes, and not being well controlled. At this time, the fetus is in a high blood sugar environment and is prone to hypoxia, especially in the late pregnancy; some pregnant women have high blood pressure, which can also cause intrauterine hypoxia; and the fetus has severe umbilical cord entanglement, which affects the blood and oxygen supply to the fetus.

In addition, there is a decline in placental function, especially in the late pregnancy, when fetal hypoxia is more obvious.

If the conditions at home allow, especially those with high-risk factors, you can rent a full-time monitor and do fetal heart rate monitoring every day after renting it home from the hospital. Because going to the hospital once a week only reflects the situation at the time, if the fetal hypoxia is not serious, it is difficult to detect.

Usually, if intrauterine hypoxia occurs after 32 or 33 weeks, hospitalization for testing may allow the fetus to survive. However, if severe hypoxia occurs during the 22 or 23 weeks, there are currently no active intervention measures.

However, the chance of fetal intrauterine hypoxia is relatively small nowadays. Most of the time, it happens after delivery. During each contraction, the placenta in the uterus may temporarily reduce the oxygen supply to the fetus. During the delivery process, the doctor will closely monitor the fetal heart rate, so there is no need to worry too much.
